T 0 all whom it may concrn:

Be it known that I, JOHN H. FELTHOUSEN, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented new and useful Improvements in Turbines, of which the following is a specication.

This invention relates to turbines and particularly to a combination turbine and bypass which is installed in a supply pipe or Conduit to adapt a water supply for use in operating a turbine to generate power for different purposes without interfering with the flow or supply of water through the pipe or conduit, or to maintain a constant quantity or flow of water through the supply pipe from the source of supply.

The preferred form of the invention consists of a turbine with the usual gates, runner and draft tube, and a by-pass supplied with gates alone and operated contrary or opposite to the gates of the turbine by a shaft having means attached to both the turbine and by-pass gates so that as the water is cut off from the turbine it is allowed to pass through the gates of the bypass, thus providing an automatic arrangement whereby the water is discharged through the turbine casing in constant quantity. The gates of the turbine and of the by-pass are respectively closed and opened equally through the medium of a governor mechanism acting upon the gate shaft, and when it is desired to have the turbine inactive its gates are fully closed, or the turbine is cut out, and simultaneously the gates of the by-pass are opened without the least loss of time or obstruction to the full flow of water through the turbine casing. The improved organization materially assists in balancing the torsion on the gate shaft and incidentally a smaller governor for regulating the turbine wheel may be used.

In its broadest aspect the invention consists in the combination with turbine gates, of a by-pass having outlet controlling means operable simultaneously with the said gates to avoid obstruction of the constant flow of water through a main or pipe.

In the drawings: Figure l is a sectional elevation of a turbine and by-pass organization embodying the features of the invention. Fig. 2 is a sectional plan view of the same.

The numeral 5 designates a supply pipe or conduit leading from a suitable supply source and having a cut-off valve and operating mechanism 6 of any preferred type. The supply pipe or conduit 5 communicates with or is attached to a turbine casing 7 which provides a receiving chamber having therein a turbine 8 cmbodying the usual accessories including a draft tube 9 which extends downwardly into a conduit or main 10 or reservoir, as the case may be, and in accordance with the application of the features of the invention. The turbine 8 and draft tube 9 are disposed at one end of the casing 7 and communieating with the opposite end of the latter is a by-pass 11 having controlling gates 12 similar to the turbine gates and located within the casing. The by-pass 11 also extends downwardly into the conduit, main or reservoir 10, as clearly shown by Fig. 1. The turbine 8 has a shaft 13 mounted in suitable bearings, as shown, and actuated by the runner 14 forming part of the turbine and disposed in operative relation to the gates 15 of the turbine. The gates 12 of the by-pass are similar in construction to the gates 15, but are operated contrary or opposite to the latter or when the gates 15 are closed, the gates 12 are opened, the gates of the turbine and of the by-pass being respectively operated through the medium of rings 17 and 18 having rods 19 attached thereto and also connected to suitable bell-cranks or analogous devices 20 on a gate shaft 21 supported by brackets 22 within the casing 7 and also exteriorly of the latter in a suitable bearing 23. The preferred form of gates is shown by Patent 921,539, dated May 11, 1909, and as the specific gate structure forms no part of the present invention it is unnecessary to further explain the same in detail, the purposes of the present invention being fullv maintained by the adoption of any suitable form of turbine gates and by-pass outlet controlling means simultaneously operable by and connected to the shaft 21. The shaft 21 has a suitable governor mechanism 24 operatively associated therewith and connected by a belt or other means 25 trained over a pulley 26 on the turbine shaft 13 for reasons well understood in this art. The shaft 13 is also provided with a suitable fly-wheel 27, and said shaft may be projected away from the turbine casing 7 and turbine 8 any suitable distance for operating an electrical generator or other mechanism.

The outlet of the by-pass 11 is formed with a conical head or dished deflector 28 within the gates 12 so as to direct the water flowing through the said gates centrally into the by-pass and avoid obstruction or retardation of the outflow of the water at all points that might otherwise ensue by water fiowing through portions of the gates counteracting a positive flow through remaining gates. The outlet extremity of the by-pass extending into the main, Conduit or reservoir 10 and which constitutes the draft tube for said by-pass is slightly deflected toward the draft tube 9, as shown by Fig. 1, so as to facilitate the outlet of the water and set up a flow in the direction of the said latter draft tube.

The turbine casing, draft tube 9 and bypass 11 will be suitably supported over the main, conduit or reservoir 10 and at points found necessary, reinforcing or strengthening structures will be applied to all of the mechanisms and elements embodied in the improved organization, and to render the casing 7 accessible interiorly for the purposes of repair or cleaning, an opening 29 is formed in one side thereof and provided with a removable cover 30.

In the operation of the device, assuming it is desired that the turbine 8 is to be used as a power generating means, the shaft 21 will have been shifted to open the gates 15 and close the gates 12 and the water entering the 'casing T through the supply pipe 5 will operate the runner ll and the shaft 18 and then flow out through the draft tube 9 into the main, conduit or reservoir 10. During the operation of the reservoir, should a grcater speed be attained than desired or should the load be lightened, the gates 15 will be proportionately closed and the gatcs 12 correspondingly opened so that the water will then flow through the turbine and continue to operate the latter and pass out through the draft tube 9 and also through the gates 12 and by-pass 11 and thereby maintain a constancy of flow of water from the pipe 5 into the main, Conduit or reservoir 10. lVhen the turbine is cut out or its operation is undesirable, the shaft 21 will be operated to entirely close the gates 15 and fully open the gates 12 and the water will then have an unrctarded flow and the quantity thereof maintained constant from the pipe 5 through the by-pass 11 to the main conduit or reservoir 10.

The improved organization will be found exceptionally advantageous for the purpose for which it has been devised and the proportions and dimensions of the several parts may be obviously varied to accommodate' different applications.
